The Sentry: Kolchak tries to find some kind of reptilian monster that has been killing construction workers after they open a new tunnel, nearly 2 miles underground. https://www.imdb.com/title/tt0621545 , https://www.youtube.com/watch?v=3wh8MtSnfMs
https://www.metv.com/lists/the-10-most-menacing-monsters-seen-on-kolchak-the-night-stalker Although this TV series was limited with a low budget, the stories are all interesting, nevertheless. Of course the alligator-humanoid was just another costume from the wardrobe department, but humanoid myths & legends have been around since ancient times. The humanoid dog or wolf, bird, piscine_and_amphibian & reptilian have all been depicted throughout history.
"An underground data-storage facility uncovers a problem when they excavate a tunnel for a new wing. Carl investigates the deaths of several employees of the facility who appeared to have been killed by a wild animal, and he discovers a rampaging reptile that has been disturbed by the digging of the tunnel. As Kolchak tries to stay one step ahead of the law, the beast continues its assault on the facility, destroying anything and everything in its quest for the eggs that have been stolen from its nest."
